"An innovative solution for the removal of PFAS in complex waste streams"
CCES has partnered with The Water and Carbon Group (WCG) to offer its foam fractionation process called The LEEF System® as a low-energy PFAS extraction and volume reduction system. Based in Australia, WCG developed the LEEF System® to treat highly contaminated wastewater such as landfill leachate or brine streams from industrial or mining activities. A key feature is that pre-treatment is typically not required for direct PFAS removal.
The technology combines a proprietary multiple step foam fractionation and enclosed solar distilling system to deliver a unique and proven PFAS solution centered around harnessing air, gravity, and the sun.
The system has been engineered to sharply reduce high energy consumption and large waste streams that plague existing systems while utilizing renewable and naturally occurring resources. Throughout the process, zero chemicals or consumables are used, resulting in a simple to operate, low maintenance system. Using a modular design, the system can be easily scaled to meet any volume requirements.
Performance
The system removes up to 100% of targeted PFAS compounds to below the analytical limits of detection within a short operating time. Less than 1% waste stream consistently generated, with further reductions possible using solar distillation.
Substantial flexibility and advantages are designed into the LEEF System® to allow for customization of operation at sites with different contamination characteristics. We understand that not every wastewater is the same and a treatment system needs to meet site-specific challenges. The modular system can be assembled to treat any volume from 5,000 gpd to 500,000+ gpd. A full-scale LEEF System® is already in operation in the City of Darwin in Australia which treats 36,000 gpd.
In 2022, LMS and WCG started demonstrating the technology at landfills in the United States and have already treated NINE diverse leachates, including reverse osmosis concentrates. Check out two of the removal charts below and visit our LEEF WEBSITE for more information.
